That sounds extremely accurate, and not for the extremes either.

Newt Gingrich & Rush Limbaugh began the mantra of refusing to compromise on any position. They are anything but extreme and are really more the torch bearers. Rush was even awarded a Presidential medal of Freedom.

And sensitivity to issues of fairness is hardly an extreme position. That's probably the most mainstream belief associated with liberalism and just plain being a good human being.

What bias?
